ArduinoVoip Incoming call accepted, Status = call!

if incoming call accepted, cannot get cancel if caller hang up the call.

If the call is answered, send call hang up command to hang up the phone

void SipMachine::bye()
{
    sipBye();
    status = idle;
}

If the caller cancels the call, esp32 will reset the state after receiving the bye command https://github.com/rousir/ArduinoVoip/blob/d09927c316491cbaf43aa2d21cc83b6f86ab5f45/src/SipHeader.cpp#L40

If the caller cancels the call : https://github.com/rousir/ArduinoVoip/blob/d09927c316491cbaf43aa2d21cc83b6f86ab5f45/src/SipMachine.cpp#L122 if caller calling and answered, speak, and caller hang up. Esp no get respondcode, still lopoping in here!

and if time experied the sip cannot re-registering! in debug show 07:27:39.221 -> sip server disconnected, reconnect... 07:27:39.256 -> Connect SIP Client on IP 192.168.43.202 Port 5060 ret= true 07:27:39.256 -> ***** Register ***** 07:27:39.256 -> REGISTER sip:192.168.43.202 SIP/2.0 07:27:39.256 -> Via: SIP/2.0/TCP 192.168.43.54:5060;branch=z9hG4bK-0Oi2Qc1Kf6Od3Ws5Sq4Pf8Tw6We5Kx 07:27:39.256 -> Max-Forwards: 70 07:27:39.290 -> From: sip:[email protected]:5060;tag= 07:27:39.290 -> To: sip:[email protected]:5060;tag=as7c2038dd 07:27:39.290 -> Call-ID: [email protected]:5060 07:27:39.290 -> CSeq: 1 REGISTER 07:27:39.290 -> User-Agent: esp32 sip 07:27:39.290 -> Contact: sip:[email protected];transport=TCP 07:27:39.290 -> Allow: INVITE,ACK,OPTIONS,BYE,CANCEL,SUBSCRIBE,NOTIFY,REFER,MESSAGE,INFO,PING 07:27:39.290 -> Content-Length: 0

Okay, I didn’t encounter this problem during the test. I have been busy recently. I will check it when I have time. The sip protocol is simple, you can use the debug information to check that the step was unsuccessful

Ok, fix now for re registering issues!

pls see the code https://github.com/rousir/ArduinoVoip/blob/d09927c316491cbaf43aa2d21cc83b6f86ab5f45/src/SipMachine.cpp#L190

its on if condition if (sipHeader.contentLength > 0) {

}

its work?

Mar 12 '21 08:03 indotronic

if (sipHeader.contentLength > 0)
{
    sipHeader.contentLength -= (str.length() + 1);
    debugL1_println(str.c_str());
    parserSdp(str);

    if (sipHeader.contentLength < 0)
    {
        exec();

        if (status == messageIn) {
            debugL1_println(str.c_str());
            messageData = str;
        }
    }
}

It works and is used to detect the content of the sip body

After receiving the call, esp needs to send the answer command many times to answer it normally? 收到呼叫后，esp需要发很多次接听命令才能正常接听？

Mar 15 '21 01:03 rousir

i think esp no send command many time.. and auto hangup after 10sec accept call

Mar 17 '21 02:03 indotronic

the call problem ended outomatic after 10 second solved.. but if caller hang up, caller not send BYE..

Mar 17 '21 09:03 indotronic

if make call not work, just show
